The SCOTUS was quite clear in its ruling in DC v. Heller.
"The operative clause’s text and history demonstrate that it connotes an individual right to keep and bear arms. Pp. 2–22."
"The “militia” comprised all males physically capable of acting in concert for the common defense. The Antifederalists feared that the Federal Government would disarm the people in order to disable this citizens’ militia, enabling a politicized standing army or a select militia to rule. The response was to deny Congress power to abridge the ancient right of individuals to keep and bear arms, so that the ideal of a citizens’ militia would be preserved."
"The
Second Amendment ’s drafting history, while of dubious interpretive worth, reveals three state
Second Amendment proposals that
unequivocally referred to an individual right to bear arms. Pp. 30–32."
